imageApproxRatio function

Syntax

  • string imageApproxRatio(searchQuery, axesRatio, n)

Parameters

  1. searchQuerystring
    Search query to apply on list of all files in the workspace. See fileSearch / filesSearch for details about the syntax.
  2. axesRatiostring
    { "xy" | "xz" | "yx" | "yz" | "zx" | "zy" }—Defines which scope axes ratio is used as a reference.
  3. nfloat
    Number (integer >= 1) of textures to consider (one is randomly picked out of the n best textures.

Returns

Texture with one of the n best ratio matches (according to axesRatio).

Description

The imageApproxRatio function returns one of the n textures with the best ratio match, from the files specified by searchQuery, according to the specified combination of axes.

Note:

imageApproxRatio(searchQuery, axesRatio, 1) == imageBestRatio(searchQuery, axesRatio)

Setting up texturing based on the best pixel ratio

The goal is to set up the texturing, depending on the best pixel ratio of the list of desired textures. The following textures all have different resolutions.

Textures with different resolutions

n = 1: "best ratio"

Lot -->
    s('0.9,'0.9,'0.9)
    center(xz)
    RecursiveSplit

RecursiveSplit -->
    case scope.sx >= 1.5 && scope.sz >= 1.5 :
        split(x) { ~scope.sx/3 : 
              split(z) { ~scope.sz/3 : 
                         RecursiveSplit }* }*
    else: Texture

Texture -->
    setupProjection(0, scope.xz, scope.sx, -scope.sz)
    projectUV(0)
    texture(imageApproxRatio(
         "/myProject/assets/textures/*.jpg", "xz", 1))
Texture with n =1

n = 3: "choose randomly one of the best three ratios"

Texture -->
    setupProjection(0, scope.xz, scope.sx, -scope.sz)
    projectUV(0)
    texture(imageApproxRatio (
         "/myProject/assets/textures/*.jpg", "xz", 3))
Texture with n = 3
